Climate Change And Idaho Agriculture: Is Farm Size A Determinate Of Adaptive Capacity?, Blair P. Vanderlugt Jan 2011

Climate Change And Idaho Agriculture: Is Farm Size A Determinate Of Adaptive Capacity?, Blair P. Vanderlugt

McNair Scholars Research Journal

Determining how agriculture will be affected by climate change is not only a question biophysical change in crop production; it also depends on the adaptation of the farmer to these changing conditions. A flaw in models using nationally aggregated cross sectional data is that the adaptive capacity of unique farms is not captured in the analysis. In order to understand the local effect of climate change on welfare models must capture attributes specific to the study area. Factors that must be taken into consideration include farm characteristics local policy and institutional frameworks (Antle et al. 2004; Mendelsohn, Nordhaus, and Shaw …


Long Term, Continuous Temperature Monitoring Of A Simple Anaerobic Digester And Open Manure Storage Pond In Eastern South Dakota, J. Darrington, E. Cortus Jan 2011

Long Term, Continuous Temperature Monitoring Of A Simple Anaerobic Digester And Open Manure Storage Pond In Eastern South Dakota, J. Darrington, E. Cortus

The Journal of Undergraduate Research

A two-cell manure storage system with a cover on the first cell was constructed in the late summer of 2009 in Eastern South Dakota. The covered cell acts as a simple anaerobic digester. Continuous temperature monitoring for 8 months shows the winter effluent temperature equilibrated to around 6°C, and that the effluent temperature trend lagged the ambient temperature trend by a month. Manure composition was also analyzed and was found to be relatively steady throughout the system. Volatile solids were the only component that dropped appreciably across the treatment cell, with an observed maximum of 50% reduction.
